Characterization of Lie centralizable mappings on B(X)
Behrooz Fadaee, Hoger Ghahramani, Ayyoub Majidi
Assume that B(X) is the algebra of all bounded linear operators on a complex Banach space X, and let W in B(X) is such that cl(W(X)) is not equal to X or W=zI, where z is a complex…
Jordan and Lie derivations of -Johnson amenable Banach algebras
Hoger Ghahramani, Parvin Zamani
Let U be a -Johnson amenable Banach algebra in which is a non-zero multiplicative linear functional on U. Suppose that X is a Banach U-bimodule such that for…
On Lie n-centralizers, n-commuting linear maps and related mappings
Hoger Ghahramani
In this article, we consider several local conditions under which linear mappings on algebras act like Lie n-centralizers and we study these linear mappings, Lie n-centralizers and…
Symmetrically pseudo-amenable Banach algebras
Hoger Ghahramani, Parvin Zamani
We introduce and study a new notion of amenability called symmetric pseudo-amenability. We obtain some properties of symmetrically pseudo-amenable Banach algebras and with examples…
